Abstract

Moteur asynchrone à rotor à cage d'écureuil, associé à un frein fonctionnant par manque de courant. Le rotor 5 comporte, à ses extrémités des bagues de court-circuit 11, 12 et une bague intermédiaire de court-circuit 13 s'étendant radialement depuis le diamètre extérieur 8 du rotor 5 jusqu'à un évidement cylindrique 15 et prévue our séparer une partie 5 du rotor 5, destinée à dévier la partie correspondante du champ radial statorique, vers le plateau mobile 20 du frein 2 dont une face radiale 19 disposée vis-à-vis de segments 17 en matière magnétique disposés radialement entre le partour 7 de la bague 12 et le diamètre extérieur 8 du rotor 5. La bague 12 s'étend radialement jusqu'à l'évidement 15.Asynchronous motor with squirrel cage rotor, associated with a brake operating by lack of current. The rotor 5 has, at its ends, short-circuit rings 11, 12 and an intermediate short-circuit ring 13 extending radially from the outside diameter 8 of the rotor 5 to a cylindrical recess 15 and provided to separate a part 5 of the rotor 5, intended to deflect the corresponding part of the stator radial field, towards the movable plate 20 of the brake 2, one radial face 19 of which is disposed opposite segments 17 of magnetic material arranged radially between the part 7 of the ring 12 and the outside diameter 8 of the rotor 5. The ring 12 extends radially to the recess 15.
